基于出行时空分布的重力模型标定方法研究
|
摘要
出行时空分布是小区出行总量随出行时间变化的分布形式,可应用于重力模型的标定.现有重力模型标定较常用逐步搜索法,其精度受限于算法中参数步长的选择.建立了一种基于出行时空分布的重力模型标定方法,并以西安市出行数据为例,通过与逐步搜索法结果对比,验证了该方法的可行性,结果显示该方法较逐步搜索法精度高,收敛速度更快.
The trip time-space distribution is the distribution form of the total amount of travel in a residential area varying with travel time, which can be applied to the calibration of gravity model. A gravity model calibration method based on travel time-space distribution was established. Taking Xi 'an travel data as an example, the feasibility of the method was verified by comparing with the results of step-by-step search method. The results show that the method has higher precision and faster convergence speed than the step-by-step search method.
